What is a metric wrench?
A metric wrench is measured in millimeters and always use whole numbers. The bolts are signified by the measurement of the wrench in this type of system. This is also known as the International System of Units (SI), it is called that as in many parts of the world, the measurements are done in meters and centimeters.
Are wrenches oversized?
RE: Bolt Hex vs Wrench Size The wrench is oversize relative to the nominal dimension, and the hex (bolt head) tolerance ranges from “right on” nominal to slightly undersized. For the 3/8″ hex example, the wrench opening (flat-to-flat dimension) is 0.378 to 0.384.

What is metric spanner?
Metric spanner sets are designed to tackle nuts and fasteners defined by millimetre sizing (as opposed to imperial inch-based kits for older fittings).
How do you measure a spanner wrench?
Measure the shaft. Spanner wrenches come in various sizes from 4 inches to 18 inches in length.To determine what size spanner wrench you have, measure from the end of the handle to the edge of the fixed side of the vise. Some spanner wrenches have the size printed on the handle.

What should the clearance be for a nut wrench?
Allowance (minimum clearance) between maximum width across flats of the nut and jaws of wrench equals (0.005W+ 0.001). Tolerance on wrench opening equals plus (0.005W + 0.004 from minimum). W equals nominal size ofwrench. cD —22 2003 Industrial Fasteners Institute
